Gas saving deflector



June 25, 19350 B. s, sMaTH GAS SAVING DEFLECTOR Filed March 21, 1934 BY Q ATTORNEY Patented June 25, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to heating appliances, and particularly to circulating room heaters, In such heaters the air as warmed is discharged into the room from the top grille of the heater cabinet and of course immediately rises. As a result the ceiling of the room where the heat is unnecessary is constantly warmer than the floor and the occupied zone of the room generally, and a relatively large amount of fuel must be burnt to maintain this zone at a desirable and comfortable living temperature.

The principal object of my invention is to overcome this uneven heating by the provision of a deflecting device, adapted to be mounted on top of the heater and so arranged that the air discharging from the top of the same will be caught and immediately deflected toward the floor. A greater percentage of the warm air is therefore retained in the room midway between the floor and the ceiling and the temperature at these two extremes is kept more nearly equal.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure l is a perspective view'of my improved deflector as applied to a standard circulating room heater.

Figure 2 is a transverse section of the same.

The heater illustrated and to which the deflector is shown applied comprises as usual the exterior heater cabinet I set with its back near the wall, said cabinet having a top cover 2 provided with grille openings 3 through which the warmed air escapes into the room. The deflector comprises a flat metal plate 4 of the same shape and substantially the same size as the top of the heater and provided all about with a depending relatively wide and outwardly flaring flange 5, which extends beyond the periphery of the top of the heater. The under side of this plate is coated with chromium, baked enamel, or other suitable heat reflecting material, while its upper side is preferably finished the same as the exterior finish of the heater cabinet. 1

The plate is supported from the top of the heater by front and back legs 6 and 1, the front legs 6 being relatively long so that the plate is disposed with an upward slope toward the front.

The legs at the bottom are bent to form feet 8 to rest on the top 2 and to also depend about the edge thereof. The back feet are preferably designed so as to engage said edge on both sides of the back corners so as to positively and yet removably locate the deflector in place without requiring the use of permanent fastening means.

The legs may be mounted on the plate for horizontal adjustment relative thereto as indicated at 9 so that the device may be accommodated to heaters whose tops vary somewhat in size.

By means of the above construction and arrangement of the deflector plate the air as it passes through the heater openings 3 is deflected toward the front of the same and is then thrown downwardly into the room from the front of the deflector. From actual tests in the same room, taken with approximately the same external temperature I found a considerable saving in fuel, accompanied by a more even temperature between the floor and ceiling of the room, was had when the heater was equipped with the deflector than without the same. With the deflector in place for instance a ceiling temperature of 94 and a floor temperature of was obtained with a gas consumption of 13 cubic feet per hour. Without the deflector on the other hand the ceiling temperature was while the floor temperature had dropped to 69, and the gas consumption jumped to 16% cubic feet.

Apart from functioning as an air deflector the deflector plate serves to prevent small articles from being dropped down the otherwise exposed grille at the top of the heater.

While I have shown and described this deflector as being mounted on a circulating heater of the type which upstands from the floor of the room, and for which type it is particularly adapted, said deflector may also be used in connection with floor furnaces.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as r defined by the appended claim.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

An air deflector for the top of a circulating room heater of substantially rectangular form, which deflector comprises a deflecting plate substantially the size of the heater top, front legs depending from the plate and formed at their 5 lower ends to removably rest on the top of the heater and overlap the front edge thereof, back legs depending from the plate, the back legs having cove shaped feet to embrace the top and adjacent side edges of the upper corners of the heater whereby such feet function to positively locate the plate in proper position on the heater and prevent lateral displacement thereof.
